strange behavior at input data : plot '-' at wgnuplot.

[Tatsuro M. <tma...@ya...>]

Hello

 .

I found strange behavior at input data : plot '-'.

gnuplot> plot '-'
input data ('e' ends) > 1 1
input data ('e' ends) > 2 2
input data ('e' ends) > 3 3  
input data ('e' ends) > 4 4 M M K 


At the screen I preessed left arrow cursor key 'M' appeared.
'K' right arrow key
'P' down arrow key
'H' or 'O' up arrow key

The phenomena happened in gnuplot 4.2.2 and the current CVS(2008-02-19).

Regards

Tatsuro

Please tell us the operating system you are using,
the version of libreadline you are using, and the
output from the gnuplot command
   show version long

Hello

My windows system is win Xp pro sp2.
The version of readline is 5.0 from the GnuWin32.

But for the wgnuplot 4.2.2, I have not built it by myseslf. 
It was downloaded from the gnuplot source-forge page.
So I do not know the version of the readline library.

Regards

Tatsuro

Hi,

As far as I remember from the last time I had to dig in that code, the 
code path for the inlined data does not use readline at all. That's why 
arrow keys generate garbage instead of editing the line.

Best regards,

Hmm. You are correct.

I have placed a patch on SourceForge to run the inline data through
readline.  

 1899013    Read inline data from '-' via readline() if available

Simple-minded testing here shows no problem, but it is
possible that it could trip up some complicated combination of 
redirected stdin and stderr.  Please give it a try.
